Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed September 5, 1905. Renewed August 29, 1906. Serial No.332,484.

To all whom it may concern:

Be it known that I, EVERITTE STEVENSON, a citizen of the United States,residing at Mitchellville, in the county of Polk and State of Iowa, haveinvented a certain new and useful Improvement in Riding-Cultivators, ofwhich the following is a specification.

The object of my'invention is to provide simple, durable, andinexpensive means whereby the operator riding upon a machine of thisclass may by a manipulation of the foot-rests of the machine steer thesupportingwheels of the machine as required to accurately direct themachine between the rows being cultivated.

My invention consists in the construction, arrangement, and combinationof the steering device, with the machine-frame and operator s seat,whereby the objects contemlated are attained, as hereinafter more iullyset forth, pointed out in my claims, and illustrated in the accompanyingdrawing, in which I have shown a perspective view of a portion of ariding-cultivator frame with my improvements applied thereto.

Referring to the accompanying drawing, I have used the reference-numeral10 to indicate the portions of the machine-frame shown. At the ends ofthe rear cross-piece of the machine-frame are the upright journals 11,in which one rotatably mounted in the upright portions 12 of thestub-axles 13. Fixed to each of the stub-axles is a forwardly-projectingarm 14, and these arms are pivotally connected by means of the cross-rod15. Fixed to the machine-frame are two han ers 16 and 17, which hangerssupport the rocIi-shaft 18, arranged longitudinally below the center ofthe machine-frame. Adjustably fixed to the rock-shaft 1 8 is an arm 1 9,pivotally connected with the central portion of the rod 15, so that whenthe shaft 18 is rocked the forward ends of the arms 14 will be movedlaterally relative to a fore-and-aft line through the machine, and thismovement will of course change the positions of the supportingwheels,and the machine will thereby be guided. On the rear end of the shaft 18is a cross-piece 20, adjustably secured thereto by the set-screw 21.Adjustably fixed to each end of the cross-piece 20 is a stirrup 22. Theoperators seat 23 is supported upon a beam 24, which beam is fixed atits forward end to a cross-piece of the frame andis adjustably fixed atits rear end to the hanger 17 by means of the bolt 25, which may bepassed throu h any of the openings 26 in the hanger 17. n this way theseat may be adjusted vertically.

In practical use the operator first adjusts the seat and stirrups asdesired, the seat being adjusted up and down by means of the bolt 25 inthe openings 26 and the stirrups being adjusted longitudinally of theshaft 18 by means of the set-screw 21. If the operator desires to directthe supporting-wheels toward the right, he pushes downwardly on theright stirrup, thus swinging the upper end of the arm 19 toward theright and moving the forward ends of both of the arms 14 toward theright, and in this way the direction of the advance of the machine maybe controlled.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is-

l. The combination of a vehicle-frame, axles mounted in verticalbearings at the side of the frame, supporting-wheels arranged verticallyand mounted on said axle, arms projecting forwardly from the axles, arod connecting both arms, brackets secured to the frame and rojecteddownwardly, a rockshaft in said rackets, an arm fixed to the rock-shaftand connected with said rod, stirrups on the opposite sides of therock-shaft and connected therewith, and a drivers seat above thestirrups.

2. The combination with a vehicle-frame, axles arranged in verticalbearings at the sides of the vehicle-frame, vertically arranged wheelson said axle, an arm fixed to each axle and projected forwardly, a rodconnecting both arms, two brackets fixed to the frame and projecteddownwardly therefrom, a rockshaft supported in said arm, an arm fixed tothe rock-shaft and connected with said rod, a cross-piece adj ustablymounted on the rear of said rock-shaft, stirrups adjustably mounted onthe ends of said cross-piece, a bar connected at its forward end of theframe and adjustably connected at its central portion with one of thearms for supporting the rockshaft and a drivers seat on the rear endthereof.
